Title: Monitoring system for machine drives
Inventor: LUDWIG RAINER
IPC: G05B19/4063
Filed: 1987-12-18
Abstract: In order to provide a simply constructed, rapidly reacting monitoring system for a machine drive operated by means of a current pulse train and electronically controlled via a pulse time duration, having a measuring device for detecting forces acting against the drive and having a comparator element for detecting overload conditions with respect to preset maximum values which emits an output signal in the event of their being exceeded, it is proposed that the measuring device detects the pulse width and that the comparator element compares the pulse width with a presettable maximum pulse width and emits the output signal in the event of an overshoot of the maximum pulse width.

Patent DE-3810883-A1 (DE)
Title: Picture generating device having a permanent-magnet stepper motor
Inventor: WATANABE JUNJI
IPC: G03G15/04
Filed: 1988-03-30
Abstract: A picture generating device according to the invention has a permanent-magnet(-type) stepper motor. When a manuscript is placed on a manuscript table and a copying operation is initiated at an operating panel (100), the manuscript is optically illuminated by means of an illuminating lamp (18) and scanned. The lamp (18) is arranged in or on a first carriage which, together with a second carriage, is driven by means of the permanent-magnet stepper motor (84) in the predetermined illumination/scanning direction. The stepper motor (84) can be controlled by a motor driver circuit (214). When the latter is fed a predetermined pulse signal from a main processor (200), the stepper motor (84) is driven to illuminate and scan the manuscript. An optical image which is gained through the illumination/scanning process is generated (built up) on a photo-conducting drum (40), developed and then transferred by a transfer charger unit (60) onto a sheet (of paper). The picture which is transferred to the sheet is fixed thereon by means of a fixer unit (66). <IMAGE>
Patent DE-3812316-A1 (DE)
Title: Method for determining the axis position of a robot
Inventor: MEIER CHRISTOF DR ING
IPC: B25J9/16
Filed: 1988-04-13
Abstract: If drives (A1, A2, A3) for individual axes of a robot (R) act on the assigned axes via transmission paths guided by means of the robot (R), it is possible that, without moving a drive (A1, A2, A3), the axis assigned to the latter can change its position by the movement of intermediately connected axes. If the position determination is carried out by means of position transmitters arranged on the drives (A1, A2, A3), the position changes produced by such a coupling cannot readily be detected. According to the invention, the mechanical axis coupling is electrically simulated by coupling modules (K<-1>, K). By this means, the robot (R) can be precisely positioned and error-free position feedback takes place. The movement of the robot (R) remains reliably limited to the permissible movement range. <IMAGE>
Patent DE-3812666-A1 (DE)
Inventor: BOETTGER DETLEV
IPC: H04M3/42
Filed: 1988-04-15
Abstract: To provide the possibility for an external call connection in the event of a fault preventing normal switching operation (mains failure, severe software error), a preferred subscriber station (T1) is directly connected to a predetermined exchange line. If such subscriber stations are conducting external calls when a fault occurs, these are not released during the transition from normal switching operation to emergency operation or during the transition in the reverse order to this. If the exchange line (AL1) is occupied by its associated preferred subscriber station (T1) via the corresponding connector unit (AS), the time delay otherwise existing during the switch-over of the change-over unit (U) is cancelled. If this exchange line (AL1) is seized by another subscriber (Tn), the existing call connection is released by the delayed switch-over. If a call connection exists for a preferred subscriber station, a switching path is first built up to the relevant connector unit (AS) during the transition from emergency mode to normal switching operation and the speech path is prepared. It is only then that the exchange line is connected to this preparatory path by the connector unit (U). <IMAGE>

Title: Injection device
Inventor: ROZSAS TOMAS DR ING
IPC: F02M69/44
Filed: 1988-05-26
Abstract: A device for the injection of a fuel-air mixture into the intake line (2) of a mixture-compressing, multicylinder internal combustion engine (1) is described, which has a fuel injection valve (7), which introduces the liquid fuel into a support air flow derived from the intake line, and the injection lines (10, 11) transporting the fuel-air mixture to the injection points assigned to the individual cylinders of the internal combustion engine. In order to be able to transport the additional quantity of fuel, necessary in the event of sudden load increases of the internal combustion engine (1), to the cylinders of the internal combustion engine without the need for a constantly running feed pump, it is proposed according to the invention that a device (15), automatically becoming operative at higher loads of the internal combustion engine, be provided for boosting the support air flow. The said device is suitably formed by a diaphragm pump device (15), actuatable by the intake pipe vacuum, which has a diaphragm (16), adjustable by a diaphragm spring (17) against the intake pipe vacuum. <IMAGE>

Title: Fish-clearing device for a tank for intensive fish fattening
Inventor: GOETZ HELMUT
IPC: A01K61/00
Filed: 1988-08-18
Abstract: The fish-clearing device comprises a frame which extends over the outline of the tank and can be displaced over the height of the tank (10) and lowered as far as its bottom. Provided in the frame are two large-area passage openings (28) for fish, which can be closed with a shutter (32). The shutter (32) is water-permeable but not passable for the fish. The fish-clearing device is lowered into the tank with the shutters (32) opened and, after the shutters (32) have been closed, raised slowly. The fish are thus driven to the water surface where they are removed in a landing net. At the end of its lift, the fish-clearing device pivots about a stop on the upper tank edge, as a result of which the last fish collect in a channel (66) close to the operating jetty (62). The frame can be collapsible. <IMAGE>

Patent DE-3837560-A1 (DE)
Title: Process for the gassing of agricultural materials stored in storage sheds
Inventor: BOSCQ JEAN ROBERT
IPC: A01M17/00
Filed: 1988-11-04
Abstract: For the gassing of low-level stores or bulk stores for cereals with toxic gassing agents, the procedure has hitherto been that these gassing agents were applied to the prepared stores and the sealing-off of the store took place subsequently, with generation of the gassing gas aready commencing. In this working technique, as a rule, gas concentrations which are above the MAK value and can thus lead to health risks are obtained in the air space above the storage material. Furthermore, in this method, the necessary quantity of gassing agent is increased. In the process according to the invention, first a sealing-off/covering of the cereal store with gas-tight tarpaulins is produced, and subsequently the gassing agent is introduced into the cereal through orifices made or opened at a later stage. The orifices are closed again immediately. The gassing agent is thereby utilised as efficiently as possible and the danger of the escape of the gassing agent and risk to the work personnel are reduced considerably. Agricultural storage, especially gassing in the storage of cereal in low-level and bulk stores.

Title: Bending machine for steel reinforcing mats
Inventor: BOCK RUDOLF
IPC: B21D11/12
Filed: 1988-11-17
Abstract: In the bending machine for steel reinforcing mats, an abutment rail interacting with a bending beam (15) is designed as a plate (22) which is held along one longitudinal side by a sturdy holding beam (19) and, at its free longitudinal edge, has a continuous bending mandrel (24) which protrudes on both sides beyond the plate (22), i.e. has a larger diameter than the thickness of the plate (22). Around this relatively narrow bending mandrel, it is possible to produce above the plate (22) and unhindered by the holding beam (19) reinforcing cages (28) of different shapes and sizes, and, because of the shape of the plate and its small thickness in comparison with the diameter of the bending mandrel, it is possible to execute bending angles on the steel reinforcing mat of up to 200@ in the formation of hooks on the latter. <IMAGE>
